The photo was taken during the mechanical control conducted by FAO as part of cash-for-work activities, funded by the World Bank. One of the most economically destructive plant pests in the entire world is the Moroccan locust. They have five growing stages also called instars. Early stages (1st to 3rd instars) are easier to mechanically control. but if the locust population is not controlled and they reached the adulthood stage, they will grow wings and make swarms which will be almost not possible to mechanically control them and will create huge problems for agriculture and food security.
In Baghlan province, FAO has conducted cash-for-work activities for the people of the affected communities to mechanically control the outbreak of Moroccan locust at the early stages to reduce the negative impact of the outbreak.
